毛细管电泳用于药物分析的研究进展

药物分析是毛细管电泳（CE）的重要应用领域，所有CE分离模式与检测方法都在各种药物及其不同形式样品的分离分析中显示出特色和应用能力。该文从药品分析领域中的小分子药物（包括手性药物）及其有关物质、中药与天然产物、体内药物分析、生物制品药物分析等几个方面，综述了近几年CE在这些传统药物分析领域应用的研究进展。限于篇幅，未包括现代药物分析研究比较活跃的理化常数测定、亲和毛细管电泳与结合常数研究（药物与受体间的相互作用等）、临床生物标志物分析、代谢组学和微流控芯片CE分析等方面的内容。根据目前传统药物分析领域的发展，该文关注到近期CE在顺应药物分析的法规需求、电容耦合非接触电导检测（CE-C⁴ D）、改进检测灵敏度与精密度、CE-十二烷基硫酸钠（SDS）毛细管电泳、全柱成像毛细管等电聚焦（icIEF）、抗体分析等方面的新进展。该文结合文献，讨论了目前传统药物分析领域的需求，以及CE在其中的地位、挑战和机遇。对目前CE主要作为互补分析方法在化学药和中药分析中的应用研究提出了一些针对性的建议，期待CE在生物制品分析中的特色和能力得到进一步的发挥，同时提出CE-MS和对CE分析重复性改进等新进展可能对未来CE应用领域的大幅度扩展。该综述主要涉及近3年（2017年1月到2020年2月）及部分2016年的相关文献。

Advances in application of capillary electrophoresis in pharmaceutical analysis

Capillary electrophoresis (CE) is mainly applied in pharmaceutical analysis. All CE separation modes and detection methods show their characteristics and application abilities in the separation and analysis of different drug samples. The present review provides a brief cross section of new advances in CE application in pharmaceutical analysis, including for small molecular drugs and related substances (including chiral drug separation), traditional Chinese medicine and natural products, in vivo pharmaceutical analysis, and biological product analysis. However, the research on physical and chemical constant determination, affinity capillary electrophoresis and binding constant research (drug and receptor interaction, etc.), clinical biomarker analysis, metabolomics, and microchip CE analysis are not included. According to traditional pharmaceutical analysis developments, the recent advances in CE in compliance with pharmaceutical analysis regulatory requirements include CE capacitively coupled contactless conductivity detection (C⁴ D), improved detection sensitivity and precision, CE-sodium dodecyl sulfate (CE-SDS), imaged capillary isoelectric focusing (icIEF), antibody analysis, and so on. Combined with the references, this review also discusses the current requirements in the field of traditional pharmaceutical analysis, as well as the status, challenges and opportunities of CE in it. Some suggestions on CE application as a complementary analysis method for chemical drugs and traditional Chinese medicine analysis are put forward, and the characteristics and ability of CE in biological product analysis is expected to further development. The new development of CE-MS and improvement of CE repeatability may greatly expand the field of application of CE in the future. This review covers the improvements published between January 2017 and February 2020, as well as some important CE papers published in 2016.
